`Appiitatmn niedQnovember 11, `1927. serial No. 232,630.

This invention relates generally to fastening devices and, moreparticularly, yto a certain new and useful improvement in fasteningdevices of the type commonly known as buckles. d

My invention has for an object the provision of a buckle especiallyadapted for belts,

straps, and the like, which comprises few,

conveniently manipulated parts, and which dispenses ywith teethwor othersuch more or less material-ruining gripping means for holding the buckleto the material. Y

My invention has foranother Aobject the provision of a buckle whichshall be simplep convenient, lightand compact, economical,

reliable, and elicient and satisfactory for use wherever foundapplicable.k

My invention has for still another object the provision of a bucklewhich, when once adjusted, will hold at lsaid adjusted position Myinvention has for a further objectthe provision of a buckle which shallhave no pivoted parts, apt to come out of order after limited usage butinstead will have slidable parts with Y large bearing `surfaces andadapted to grip or clamp the material there in, in either direction ofattempted relative movement between the material and the device. Y l.

Many other objects and advantages of the construction hereinshown anddescribed will be obvious to those skilled the art to which thiskinvention appertains from the disclo-v sures herein given, andwith allsuch objectsV in view, my invention resides in the novel features ofform,construction, arrangement, and combination of partsherein shown anddescribed and pointed` outv in the claims. f

In the accompanying drawing,`

Figure l is a plan view of a fragment o f a garment equipped with abuckle embodying my invention; v

Figure 2 is a longitudinal sectional view taken approximately on theline 2 2,

Figure 3 is a cross-sectional View taken approximately on the line 3 3,Figure 2;

Figure 4 is a plan view of the buckle as seen from the rear or underside;

Figure v5 is a plan view of a clasp or fastening member adapted for(zo-operation with the buckle proper; and

Figure 6 is aV modified form of fastening-y member also adapted forco-operation with .the buckle shown .in Figure 4.

Referringnowmore in detail and by ref-v erence characters to thedrawing, wherein I have illustrated preferred embodiments of myinvention, A designates a garment of any suitable type, such asknickers` for s ort wear, the lower endl of each legof wllich has aflexible band or strip l therearound adapted for adjustment ,so as totightly encircle the wearers knee, the free end ofthe stripkbeingindicated at 2. Ordinarily, so

far Ias I am aware, a buckle having a tongueV thereon adaptedvtoselectively engage in one of a series of apertures through a tab is usedfor this purpose, or a clamping member vhaving gripping teeth thereon issubstituted for the tongued buckle; but with such devices, Y

which have generally been unsatisfactory, the cloth of the garment isvery apt to become ytorn or otherwise kdamaged under strain.

To overcome these `and otherk defects,

have provided a vbuckle made of substantially Abut twoparts, whichareadapted to grip the material of one end-portionof the band or stripto prevent relative movement therebetween ineither direction after thedesired adjustment has been made, the opposed end of the band or striphaving a fastening or clasping member thereon adapted for cooperationywith the buckle in securing the ends of the strip together.

.The buckle Vproper is indicated atB and consists of a pair of flatplates 3A and 4, termed the front and r'ear` members, respectively,inasmuch as the front member is vseen as superimposed on the rear memberwhen in osition upon the garment.

aid plates are disposed in latwise abutting relation for slidablemovement longitudinally upon one another, and in order to preventlateral movement therebetween-` the sopropposite end, or, as seen inFigures 1, 3, and i 6,'7, the front plate 3 is: provided with a`cross-bar 8 and thereby formed-with parallel slotted openings 9,710, thelatter being preferably wider than the former; Integrally formed withsaid intermediate cross-bar 8,

Vloo

los p' such` ends must be sprung apart slightlybe- 'foretheh claspingmember can be `snapped Y bars. The hook ofthe front plate 3 projectsthrough the intermediate or vcentral open# ingv 11'?- of the rearpl'ate4, its bill 12A being is a prerilblly Shaped hook, the Shank or neck 1l'ot which, the two plates `3, 4, being in flatwise superposed andslidable relation, is bent to extend somewhat into the. wider openingand then bent back and spaced from the rear face ofthe plate Swith. thebill r or head 12 of the T-bar extending endwise of and substantiallyparallel with, and disposed in a plane spaced transversely from theplane of the plates, as best `seen in Figure j4. "L The. rear plate' fris formed with a spaced pair olf intermediate! cfross-barsf13, 14, andthereby provided adjacent'the cross-barst,
